SPECIIE"-ICATION forming part of Letters Patent No. 252,352, dated January V17, 1882. i

Application filed June 24, 1881. (No model.) I l fully set forth in the following specification' Aand accompanying drawings, in which- Figure 1 is a side elevation of theinner fare of the portion lof. the lawn-mower embodying my invention. Fig.2 is a section in line m Fig. l. Fig. 3 is-a section in line y' y, Fig. 4. Fig. 4 is a vertical section in line z z', Fig. 5. Fig. 5 is ahorizontal section in line a z', Fig. 4. Fig. 6 is atop or plan view of the portion ofthe lawn'mower embodying my invention.' Fig. 7 is a perspective yView of one of the pawls thereof.

Similar letters of reference indicate corre-y sponding parts in the several figures.

My invention consists of novel means for securely binding or connecting the frame of the mower.

It also consists of novel meansfor securely and adjustably attaching the braces of the h-.mdle to the frame ofthe mower.

Referring to the drawings, A-A represent the wheels of the mower, and B the shafts or axles thereof, which are cast with or connected to the plates G of the frame ofthcmower.

D represents a ratchet rim or wheel, which is cast with or secured to the wheel A on the inner side thereof, and adapted to be engaged by the pawls E E on the hub F of the gearwheel F', which latter is freely mounted on the shaft B, and communicates motion`by means of an idler to a wheel secured to the rotary cut ter of theV mower, the bearings ofthe shaft of said cutter being shown at Gr, Figs. l, 4, and 6.

Projecting horizontally inwardly from the plates C G are lugs H, cast therewith, and surrounding the lugs are brackets J, which, secured to the plates, have openings of larger di'- ameter than said lugs, the walls ot' said openings being threaded for engagement with the threadedend of a tubular, pr partly tubular, shaft, rod, or bar, K, the threads of the ends of said shaft being in reverse order, or right and left.- l f It will be seen that when the tubular ends of the shaft are screwed into the brackets J said ends encircle the lugs H, and are thus braced without by the brackets and within by the lugs, and vastly strengthened. The rod or shaft serves to'bind the plates C of the frame, and as this is assisted by the shaft of the rotary cutter, the bed-knife, and other parts of the mower, it is evident that the frame is sesurely'conn'ccted, and is consequently rm, strong, and durable.

L represents the braces of the handle M, each of which has at its inner end a segmental slot,

N, and adjacent thereto a cylindrical opening,

' the adjustment of the handle is accomplished screws S/are passed through openings in the lugsQ and forced against washers T, interposed between the heads of the screws and outer ends of the lugs, the washers being of such dimensions that they overlap the edges of the slots N and tighten against the braces L, whereby the latter are securely held.

The special construction of the pawl-and ratchet mechanism is the subject for a separate application for Letters Patent, and is not claimed in the present case.

Having thus described my invention, what I claim as new, and desire to secure by Letters P atent, is 1. In a lawn-mower, a binding rod or shaft, with tubular externally right and left hand screw-threaded ends, in combination with an- -1 nul-ar internally right and left hand screwthreaded hollow brackets which receive said cular opening P and segmental slot N, the screw S, and the washer T, alll combined and operating substantially as set forth.
